VENTlLATlNG-FAUCET.

SPECIFICATION forming part of Letters Patent No. 232,312, datedSeptember 14, 1880.

Application filed June 28, 1880.

To all whom it may concern:

Be it known that I, BENJAMIN A. STEVENS, of Toledo, in the county ofLucas and State of Ohio, have invented certain new and usefulImprovements in Ventilating-Faueets, of which the following is aspecification.

My invention relates to improvements in ventilating-faucets of thatclass in which the faucet is adapted both for supplying air to theinterior of a keg or other vessel, to facilitate the drawing of theliquid therefrom when the plug is turned to open the way or passage, andfor supplying air when the way is closed by the turning of, the plug tothe spout or discharge end of the faucet in front of. the plug, and sopreventing the creation of a vacuum behind the fluid and avoiding theslow dripping from the spout.

My objects are to simplify and cheapen such faucets, and to renderunnecessary the employment of the pistons or air-forcing devicesheretofore generally used in faucets of this class; and my improvementsconsist in providing the turning plug with a vent-hole or air-inletcommunicating with a cavity or hollow of the plug, which cavitycommunicates, when the way is opened, with a tube or air passage-wayleading to the inner end of the faucet or to the interior of the vesselto which it is applied, and communicates, when the way is closed, withthe spout or discharge part of the faucet, as will hereinafter firstfully be described, and then designated by the claims.

In the accompanying drawings, Figure 1 is a view, partly in verticallongitudinal central section and partly in elevation, representing aconvenient way of adapting my invention to an ordinary faucet, the plugbeing turned to the position to close the way and open communicationbetween the air-chamber or cavity of the plug and the spout end of thefaucet; and Fig. 2 is a view similar to that above referred to, exceptthat the passage-wayis opened and the tube for supplying air to the keg,850., in communication with the hollow of the plug. The dotted lines inthis figure are deemed sufficient to show the obvious changes whichwould be needed to adapt the faucet for being driven into place in anale or beer barrel.

A hollow plug, A, is provided with an airinlet or vent-hole, a, and witha handle, B.

(No model.)

The vent-hole supplies air to the air-chamber or cavity 0 in the plug,whether the plugway or opening I) is opened or closed.

A tube or other suitable air-channel, l), is attached to or formed withthe shank or inner part, E, of the faucet, and this tube communicateswith the plug-cavity by an opening or air-outlet, (I, when brought inline by turning the plug, as shown by Fig. 2. At the end of theshankthat part which is screwed or driven into the vessel-an opening ortwo openings, (2, are provided.

Communication between the air-supplied cavity of the plug and the spoutor discharge end F of the faucet is made bya groove or surface-channel,f, in the plug. (See Fig. 1.) Instead of this groove, on the outside ofthe plug communicating at top with the air-chamber outlet-opening d andat its lower end with the passage-way of the spout portion of the faucetwhen adjusted as in Fig. 1, a second hole drilled through the wall ofthe plug into its cavity about at the point where the groove fterminates at its lower end might be substituted. I prefer the groove,however, as the supply of air to the spout in this way is from a higherpoint in the air chamber or cavity 0, and there is consequently noliability of the supply of air behind the liquid in the spout beingprevented by a partial tillin g of the airchamber with the liquid as itpasses through the faucet-way or passage G.

It will readily be understood from the foregoing description that whenthe plug is turned to close the way air rushes in from the front of theplug and behind the liquid in the spout F, thus rapidly freeing it fromthe beer, 850., and avoiding the slow dripping as from an ordinaryfaucet, and this, too, without requiring any additional manipulation,such as operating a plunger to pump air in behind the liquid, asheretofore.

I claim as of my own invention 1. The plug provided with the air-chamberor cavity supplied by the air-inlet or vent-hole, and communicating withthe spout portion of the faucet when the way is closed, substantially ashereinbefore set forth.

2. The combination of the airchannel in the faucetshank and the turningplug provided with the air-supplied chamber or cavity, havingcommunication with said air-channel when the wayis open and supplyingair to the faucet spout when the way is closed, substantially as and forthe purpose hereinbefore set forth.

5 3. The combination, substantially as hereinbefore set forth, of theturning plug having the vent-hole or air-inlet, the air chamber orcavity, the airoutlet or opening and the inclined groove commnnicatin gat top therewith,

to the air-channel in the faucet-shank communil eating with saidair-outlet when the way is open and the faucet -sp0ut communicating withthe air-chamber by the inclined groove when the way is closed.

In testimony whereof I have hereunto sub- :5 scribed my name.
